The RSM US Middle Market Business Index 

MMBI declines amid slowing global growth, heightened uncertainty

September 19, 2019

RSM US LLP and The Harris Poll collect business outlook data from middle market firms via quarterly surveys of the Middle Market Leadership Council survey panel. The panel consists of 700 middle market executives and is designed to accurately reflect conditions in the middle market. A reading above 100 for the RSM US Middle Market Business Index (MMBI) indicates that the middle market is generally expanding; below 100 indicates that it is generally contracting. The distance from 100 is indicative of the strength of the expansion or contraction. The MMBI was created in 2015 and is the original business index focused on the U.S. middle market.

RSM US LLP and The Harris Poll have collected data on middle market firms from quarterly surveys that began in the first quarter of 2015. The survey is conducted four times a year, in the first month of each quarter: January, April, July and October. The survey panel, the Middle Market Leadership Council, consists of 700 middle market executives, and is designed to accurately reflect conditions in the middle market.

The data for each quarter are weighted to ensure that they correspond to the U.S. Census Bureau data on the basis of industry representation. A reading above 100 for the MMBI indicates that the middle market is generally expanding; below 100 indicates that it is generally contracting. The distance from 100 is indicative of the strength of the expansion or contraction. Read more about how the index is constructed.
